IOKernelDebugger: Kernel debugger nub.

Typedefs

IODebuggerLockState
IODebuggerRxHandler
IODebuggerTxHandler

IODebuggerLockState


typedef enum { 
    kIODebuggerLockTaken = 0x1 
} IODebuggerLockState;

Constants

kIODebuggerLockTaken: Set if the debugger lock was taken.

Discussion

Defines flags returned by IOKernelDebugger::lock().

IODebuggerRxHandler


typedef void ( *IODebuggerRxHandler)(
    IOService *target, 
    void *buffer, 
    UInt32 *length, 
    UInt32 timeout );

Fields

target: The target object.
buffer: KDP receive buffer. The buffer allocated has room for 1518 bytes. The receive handler must not overflow this buffer.
length: The amount of data received and placed into the buffer. Set to 0 if no frame was received during the poll interval.
timeout: The amount of time to poll in milliseconds while waiting for a frame to arrive.

Discussion

Defines the receive handler that must be implemented by the target to service KDP receive requests. This handler is called by kdpReceiveDispatcher().

IODebuggerTxHandler


typedef void ( *IODebuggerTxHandler)(
    IOService *target, 
    void *buffer, 
    UInt32 length );

Fields

target: The target object.
buffer: KDP transmit buffer. This buffer contains a KDP frame to be sent on the network.
length: The number of bytes in the transmit buffer.

Discussion

Defines the transmit handler that must be implemented by the target to service KDP transmit requests. This handler is called by kdpTransmitDispatcher().
